Further, as shown in fig. 2, 3, 5 and 6, the second contact assembly 32 further includes a limiting member 33, and the limiting member 33 is disposed on the connection line 34 of the second contact member 322. When the seat 101 is engaged with the vehicle body 102, the connecting line 34 movably passes through the through hole 21 of the second mounting plate 20, the limiting member 33 and the elastic member 321 are respectively located at two opposite sides of the second mounting plate 20, and the limiting member 33 can be engaged with the second mounting plate 20 to limit the deformation stroke of the elastic member 321. Specifically, when the electrical connector 30 is used in the scooter 100, the first contact assembly 31 is disposed on the seat 101, the second contact assembly 32 is disposed on the body 102, wherein the elastic member 321 is disposed on one side of the second mounting plate 20 of the body 102, the connecting wire 34 passes through the second mounting plate 20, the limiting member 33 is engaged with the connecting wire 34 and is respectively disposed on two opposite sides of the second mounting plate 20 with the elastic member 321, and the limiting member 33 is disposed at an interval from the second mounting plate 20 in a stable state (after the first contact member 312 and the second contact member 322 are not connected or are stably connected).

When the seat 101 is engaged with the car body 102, the first contact assembly 31 moves along with the seat 101 toward the second contact assembly 32, the first mounting plate 10 and the second mounting plate 20 approach each other, the first contact member 312 and the second contact member 322 attract each other, the second contact member 322 drives the main body portion 3212 to move toward the direction away from the second mounting plate 20, the second contact member 322 drives the connection line 34 and the stopper 33 to move, at this time, the first elastic arm portion 3211 and the second elastic arm portion 3213 both elastically deform, the kinetic energy generated during the movement of the second contact member 322 is absorbed by the elastically deformed first elastic arm portion 3211 and the second elastic arm portion 3213, when the stopper 33 abuts against the side of the second mounting plate 20 away from the elastic member 321, the first elastic arm portion 3211 and the second elastic arm portion 3213 cannot continuously elastically deform, and the main body portion 3212, the second contact member 322 and the connection line 34 are in a relatively stationary state, the second magnetic portion 3221 is magnetically coupled and electrically connected to the first magnetic portion 3121. With the continuous installation of the seat 101, the first installation plate 10 continues to be close to the second installation plate 20, the first elastic arm portion 3211 and the second elastic arm portion 3213 gradually recover to be elastically deformed, the connection line 34 and the limiting member 33 move in the opposite direction relative to the second installation plate 20, and after the seat 101 is installed in place on the vehicle body 102, the first elastic arm portion 3211 and the second elastic arm portion 3213 are both in an elastically undeformed state, and the limiting portion is again spaced from the second installation plate 20.

Through setting up the limiting part 33, utilize the limiting part 33 and the restriction of the realization of the second mounting panel 20 to the elastic component 321 deformation stroke, avoid the too big condition that leads to the elastic component 321 to damage of elastic component 321 elastic deformation, further guaranteed the reliability of electric connector 30.

It should be noted that the via hole 21 is disposed on the second mounting plate 20, the diameter of the via hole 21 is greater than the outer diameter of the connection line 34, so that the connection line 34 can move relative to the via hole 21, and by setting the connection line 34 and the via hole 21 to move relative to each other, on one hand, the connection line 34 can be guaranteed to move relative to the second mounting plate 20, on the other hand, the connection line 34 can be enabled to move in the radial direction of the via hole 21, so that it is guaranteed that the first contact element 312 and the second contact element 322 are adaptively adjusted in the connection process, and the connection effect between the first contact element and the second contact element is improved.

Further, as shown in fig. 2, 3 and 5, the limiting member 33 is an annular structure, and the limiting member 33 is sleeved outside the connecting wire 34 and is fixedly connected to the connecting wire 34. Specifically, the limiting member 33 is configured as an annular structure, and the limiting member 33 is coaxially sleeved on the connecting wire 34, so that when the limiting member 33 abuts against the second mounting plate 20, the circumferential force of the connecting wire 34 can be uniformly applied, and the force is transmitted to the first contact member 312 and the elastic member 321 by using the connecting wire 34, thereby avoiding the first contact assembly 31 from being biased, improving the connection precision of the first contact assembly 31 and the second contact assembly 32, and further improving the stability of the electrical connector 30.

In some embodiments, the limiting member 33 and the connecting wire 34 are of a split structure, and they may be fixed by bonding or the like.

In some embodiments, the limiting member 33 is an integral structure with the connecting wire 34, and the limiting member 33 is a convex ring structure formed on the outer surface of the connecting wire 34.

Further, as shown in fig. 6 or 7, a channel 22 is further provided on the second mounting plate 20, the via hole 21 is communicated with an edge of the second mounting plate 20 through the channel 22, and the channel 22 is a straight channel or a bent channel. Specifically, when the connecting wire 34 needs to be arranged inside the through hole 21, the connecting wire 34 enters the through hole 21 through the channel 22 and the position where the channel 22 penetrates through the edge of the second mounting plate 20 in sequence, and the convenience in mounting the connecting wire 34 is improved.

In some embodiments, as shown in fig. 6, the channel 22 is a straight channel, i.e. the channel 22 extends in a straight direction, the width of the channel 22 being smaller than the diameter of the via 21 and the diameter of the connecting line 34. In the process that the connecting wire 34 enters the via hole 21, the connecting wire 34 is elastically deformed; when the connecting wire 34 enters the via hole 21, the elastic deformation is recovered, and at this time, the connecting wire 34 cannot enter the channel 22 and is separated from the position communicated with the via hole.
